Technical details

Endpoint

GEThttps://api.thetrustlayer.xyz/agent/%7BagentId%7D

When to prefer

Use this endpoint when you need a quick, lightweight trust summary for a specific agent before deciding whether to call or pay for its services. It is the fastest single-agent reputation check and is ideal for pre-flight trust gating in autonomous agent workflows. Prefer the full forensics endpoint if you need Sybil detection details or reviewer weighting breakdowns.

Side effects

Agent ID not found — returns 404 if the agentId does not exist in the registry
Invalid agentId format — returns 400 if the chain:id format is malformed or chain is unsupported
Payment failure — returns 402 if x402 micropayment is not provided or insufficient
Rate limiting — returns 429 if too many requests in a short window
Agent on unsupported chain — returns 404 if the chain is not among the 20 indexed chains
